IMPROVEMENT IVN MACHINES FOR WARPING YARN.

The Schedule referred to in these Letters Patent and making vof the same.

, To all persone to whom these presents may come:

Beit known that I, DANIEL HUssaY, of Lowell, of the county of Middlesex and, State of Massachusetts, have made a new and usefulinvention having reference to Wal-pers or Machinesfor Wai-ping Yarns; and do hereby declare the-sameto be fullydescribed in the following specification and represented iu the accompanying drawing,'of which Figure l' isa top view, and

Figure 2, a side elevation of a portion of a warper with my addition thereto; v

The object of the invention is to enable an attendant, while thawarper` maybe in operation at a slow speed, or without having to stop it, as has heretofore been the custom, tu successively remove the spools and substitute others, and effect the tying together of-the endstobe joined. i y

By thus changing the spools one after another, or in succession, the knots `formed by the tying of the yai'nswof the spools to the warped yarns will be distributed a few, inches, more or less, apart, instead of coming all together in gor about in line, across the beam, asthey usually do when the 'warper is stopped' and the spools are changed.

rIhe usualfspeed of the surface of a warper-cylinder or beam is about sixty yards per minute. When it is revolved by the additional mechanism the speed will" generally be brought down to pne and one-half yard` per minute, or thereabout. '.lhis slow rate of speed will enable `each spool to be` removed and its yarn tied to a yarn from the beam, each knot being thu's brought iin the line of the warps at a distance from that previously tied. Ihus the series of knots, instead ot' ranging square across theV Warp, or about so, will run obliquely of it, and the knots will be at `such considerabledistances apart as may be required.

In the drawingl A denotes the warperffi'ame,

B, the shaftor roller, through-the agency of which the warp-beam -or cylinder is to he revolved, there being a spur-gear, O, lixcd on the outer end of such shaft or roller. i l

'Ihis gear engageswith a spur-pinion, D, fixed on the drivinglshaft E, on which is a fast-pulley, VF, and

'a loose-pulley, G.I

The belt for drivin'glfthe-.shaft E isto run on the pulley F, and, as is customary, is to be provided with means' for shifting it from one pulley to the other, as

4occasion may require.

In advance of the above-mentioned gears is au arm or lever, H, which, at its lower end, is supported on a pivot, a, projecting frpm the lframe A.

shaft, d, carrying a worm or screw, e, to engage with vthe gear C when thel arm is drawn into a vertical position.

On Vthe upper end of the shaft d abevekgear, f, is hired, which engages with a bevel-pinion, g, fixed on a short horizontal shaft, h, duly supported in aprojectionyi, from the arm, and provided with a drivingpulley, k, disposed in range with the loose pulley G.

A handle, l, is extended upward from the part fi, and there is a stop, fm, projecting from the frame A, such stop being for arresting the arm H when moved so as to disengage the worm or screw e from the gear O.

:When the driving-belt is running on the loose-pulley,if we draw forward the arm H so as to bring the periphery of the pulley k up' against such belt, the latter will put such pulley k in revolution, whereby the bevel-gears and the worm will be set in operation so as to impart a slow rate of speed to the large gear C, the latch, when the arm H is drawn up, taking upon the stud c, and thereby retaining the worm -in Aengagement with the' gear so long as may {fe-required.

By raising the latch and moving the arm H back against the stop m the said worm will be disengaged from the gear. Ihe driving-belt may next be shifted upon the fast-pulley, so as to impart motion to the mechanism for producing the fasterspeed of the warpcylinder or beam.

I claim- 1 1. In combination with a warper, a mechanism, substantially as described, or its equivalent, for running the warp-cylinder at a rate of speed such as will allow anattendant to change each spool and substitute a fresh one, and tie its thread `to the warp, such mechanismA being the arm H, its latch b, stud o, shaft d, worm e, bevel-gears f g, and driving-pulley k, arranged with the warp-cylinder operative machinery, and to operate therewith, as explained.

2. The said'additional mechanism, or combination and arrangement of the arm H,'the latching devices b c, the bevel-gears j' g, the worm e, and the drivingpulley k, applied together and' for'use in manner as described.

DANIEL HUSSEY.
